When the file system is disabled, no data can be written to the disk. Although some minor file system operations still work, most simply return EIO. The only thing that can be done when the file system is disabled is to do a umount and run a full fsck.

Although a log replay may produce a clean file system, do a full structural check to be safe.

The file system usually becomes disabled because of disk errors. Disk failures that disable a file system should be fixed as quickly as possible.

See the fsck_vxfs(1M) manual page.
